Gastric erosion occurs when the mucous membrane lining the stomach becomes inflamed. Specifically, the term "erosion" in this context means damage that is limited to the mucosa, which consists of three distinct layers: the epithelium (in the case of a healthy stomach, this is non-ciliated simple columnar epithelium), the basement membrane, and the lamina propria.
Upper gastrointestinal bleeding can be caused by peptic ulcers, gastric erosions, esophageal varices, and rarer causes such as gastric cancer. The initial assessment includes measurement of the blood pressure and heart rate, as well as blood tests to determine the hemoglobin.
Peptic ulcer disease; Infections, such as tuberculosis; and infiltrative diseases, such as amyloidosis. A rare cause of gastric outlet obstruction is blockage with a gallstone, also termed "Bouveret syndrome" or "Bouveret's syndrome". In children, congenital pyloric stenosis / congenital hypertrophic pyloric stenosis may be a cause.
Ulceration erodes the gastric mucosa, which protects the tissue of the stomach from the stomach acids. Peptic ulcers are most commonly caused by a bacterial Helicobacter pylori infection. [5] Epstein–Barr virus infection is another factor to induce gastric cancer. [6] [7] As well as peptic ulcers, vomiting blood may result from abnormal ...
Peptic ulcer disease is when the inner part of the stomach's gastric mucosa (lining of the stomach), the first part of the small intestine, or sometimes the lower esophagus, gets damaged. An ulcer in the stomach is called a gastric ulcer , while one in the first part of the intestines is a duodenal ulcer . [ 1 ]
Covacci et al. sequence the CagA gene, which encodes for a cytotoxin-associated surface protein, which correlated strongly with strains of H. pylori that caused duodenal ulcers. This was the first description of a virulence factor for H. pylori infection determined by molecular techniques. [54] Gastric cancer 1994
Many stomach diseases are associated with infections. In the past it was widely but incorrectly believed that the highly acidic environment of the stomach would keep the stomach immune from infection. Many studies have indicated that most cases of stomach ulcers, gastritis, and stomach cancer are caused by Helicobacter pylori infection.
A peptic ulcer is a defect in the inner lining of the stomach or duodenum typically due to excessive stomach acid. Extension of the ulcer through the lining of the digestive tract results in spillage of the stomach or intestinal contents into the abdominal cavity, leading to an acute chemical peritonitis.
